Rework rendering for improved performance Approx 10-20% gain avg across several "benchmarks": x11perf, gtkperf, glxgears Moves from a single pre-alloc'd urb protected by a long-held mutex To a list of (4) pre-alloc'd urbs which can be dispatched asynchonously Improved rendering algorithm to hardware with lower CPU consumption, fewer system memory accesses, and slightly higher compression. Better scalability to multiple processors, especially with multiple framebuffers active. Signed-off-by:

Rework probe to use refcounts and std functions Because the different parts of the driver (usb, fbdev) tear down in different orders, the driver previously could crash accessing data that had already been freed. Refcounting system used to handle. Reworked probe to make use of refcounts, set mode using std fbops, and set up sysfs and pre-allocated urbs. Signed-off-by:

Add sysfs controls for edid and performance metrics There are 8 new files exposed in /sys/class/graphics/fb* edid - returns 128 byte edid blog, suitable for parsing with parse-edid metrics_bytes_identical metrics_bytes_rendered metrics_bytes_sent metrics_cpu_kcycles_used metrics_misc and metrics_reset, which resets all perf metrics to zero The 6 perf metrics are of type atomic_t. So these metrics return precise results for short benchmarks, but any test approx a minute or longer runtime may roll over. Signed-off-by:

Move to more consistent naming scheme All udlfb functions start with udlfb_ All functions for udlfb's fbdev interface start with udlfb_ops_ All functinos for udlfb's usb interface start with udlfb_usb_ Signed-off-by:

Add functions to pre-allocate and free usb bulk urbs for core render path. Udlfb currently allocates a single urb, guarded by a mutex, that is a key bottleneck. Because udlfb sends so much data, preallocation is most efficient. Functions will be used by new rendering functions in later patches. Signed-off-by:

It turns out that Mimio has a userspace solution for this product using libusb, and the in-kernel driver is just getting in the way now and causing problems. So they have asked that the in-kernel driver be removed. As the staging driver wasn't quite working anyway, and Mimio supports their libusb solution for all distros, I am removing the in-kernel driver. The libusb solution can be downloaded from: http://www.mimio.com/downloads/mimio_studio_software/linux.asp Cc: <mwilder@cs.nmsu.edu> Cc: Phil Hannent <phil@hannent.co.uk> Cc: Marc Rousseau <Marc.Rousseau@mimio.com> Cc: stable <stable@kernel.org> Signed-off-by:
